Terminal 1–2
Thessaloniki flies passengers through one connected building that the airport itself refers to, in different corners of its own site, as Terminal 1 and Terminal 2. Fraport Greece's profile for the airport lists a 34,100 m² new terminal built "as the expansion of the existing" one, alongside a refurbishment of that original building: together they raised check-in counters from 30 to 44 (+45%), security lanes from 6 to 14 (+115%), departure gates from 16 to 24 (+50%) and baggage-reclaim belts from 4 to 7 (+75%). One of the airport's four lounges, "The Lounge" Thessaloniki, confirms it sits inside what its own page calls "the new terminal" of the complex.
For connecting passengers without a boarding pass, or whose bag was not checked through, the airport routes you to reclaim your bag at the arrivals belt and go to the check-in counters in the departures area (level 1). Boarding-pass holders connecting from a Schengen flight, with baggage checked through, can instead use a separate entrance — No. 5 — straight to the departure gates on the upper level.
Pack anything liquid, gel or aerosol into containers no bigger than 100 ml apiece, all fitting inside a single one-litre resealable bag — the checkpoint hands those bags out free. A duty-free bottle bought airside can exceed 100 ml only if it stays inside its sealed, receipt-visible Security Tamper Evident Bag until you land. Ask your airline whether it offers the checkpoint's fast-lane service. Since 12 October 2025, the EU's Entry/Exit System has been rolling out at the border here too, and the airport is telling passengers flying beyond Schengen to show up the moment check-in opens, because emigration control is running slower than the old routine.
There is no shuttle or train between Terminal 1 and Terminal 2 because they are not separate buildings to begin with — the airport's own wayfinding treats them as one arrivals hall with numbered exits: the taxi rank sits between them, at exits 3 and 4, and the public bus terminal is right at Exit 4, in front of Terminal 1.
Passengers who need help because of reduced mobility should flag it with the airline or travel agent 48 hours ahead of the published departure, then look for the airline's check-in desk or the airport's own PRM point once you land. That advance warning triggers Regulation (EC) 1107/2006 and ECAC Doc. 30 response times: departing, 80 out of 100 pre-notified PRM passengers get met within 10 minutes of checking in at the point, 90 within 15, everyone within 20; landing, the same tiers apply counted from "on chocks" — 5, 10 and 20 minutes. An assistance dog travels under the identical 48-hour rule, so long as its carriage follows the usual regulations.
